Swift LCD Control Panel Problems

Hi, Just wondered if anyone has had or is having problems with their control / display panel on their Swift / Ace / Bessecar MH like us. Ours is a Bolero 680FB 2008 and when on mains or battery, after 30mins to 1 hour the right hand half of the control panel 'reverses' itself to display a mirror image of what the correct display should be and some of the figures are corrupted.

Todds motorhomes are being very helpful, but reckon this is an problem to do with the changeover in electrical component supply from Nord to Sargent ( or vice versa ) and my panel the NE183 is no longer available (?). They have had a circuit board replaced already but still no improvement and are taking it up with Swift and Nord again

Everything seems to work ok but this panel display thing is a real pain. Any suggestions anyone?
